Subject: [PATCH 09/14] bootm: Initialize bootm_data defaults in single place
Date: Fri, 22 Jan 2016 08:32:27 +0100	[thread overview]
Message-ID: <1453447952-30818-10-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1453447952-30818-1-git-send-email-s.hauer@pengutronix.de>

Both the bootm and the boot code initialize the struct bootm_data
with defaults from the bootm global variables. Create a common
function for doing this.
